AUXILIARY LUBRICATOR.

Application filed September 1, 1925.

This invention relates to new and useful improvements in an auxiliary lubricator.

One object of the invention is to produce a lubricator of the character described specially designed for application to an internal combustion motor and provided to carry a surplus supply of lubricant and to feed the same into the motor crank case, from time to time, as the normal supply in the crank case is consumed.

Another object of the invention is to produce a lubricator, of the character described, which is of such construction that the lubricant contained therein will be fed from time to time, and automatically to Jthe motor crank case, and in such quantities as will keep the lubricant in said crank case, at the desired level.

A further feature of the invention resides in the provision of a novel combination including a gauge whereby the proper operation of the lubricator is made visibly evident.

A still further feature of the invention resides in a novel type of containing tank which is so constructed as to be air tight.

It is also an object of the invention to provide a lubricator, of the character described, which is comparatively simple in construction, which may be cheaply produced, easily installed, and which is very effective in operation.

lith the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a side elevation of the motor of a motor vehicle, with the auxiliary lubricator applied thereto.

Figure 2 shows a vertical sectional view of the lubricator tank, and connections.

Figure 3 is a cross sectional view thereof, taken on the line 3 3 of Figure 2.

Figure 4: shows a vertical sectional view of the valve mechanism employed, and

Figure 5 shows a vertical sectional view of the feed chamber and connecting` parts.

Referring` now more particularly to the drawings, wherein like numerals of refer- Serial No. 53,955.

ence designate similar parts in each of the figures, the numeral 1 designates the lubricator tank, preferably formed of cast brass heads which are soldered to the ends of a sheet brass barrel. The lower head has suitable ears, as 2, providing means whereby the tank may be bolted to the cylinder head of the motor 3, The lower tank head has a transverse bore, or channel 4 which terminates in a central outlet opening 5, in the bottom of the tank which is surrounded by the valve guides 6. A feed tube 7, preferably of copper is 'connected into the outer end of the channel 4l. There is a transparent gauge tube 8, whose ends are anchored in the air tight glands 9, 9, carried by the respective tank ends and the respective ends of this gauge tube are connected into the channel l, at one end and into the top of the tank, through the port 10, at the other end.

There is a feed tank 11, preferably formed of aluminum. The lower end of the feed tube 7 is fitted through the upper end of this feed tank and is secured therein by a suitable gland, as 12. The lower end of the feet tube extends down into the feed chamber 13 in the feed tank, and is free. The lower end of the feed ,chamber 13, beneath the free end of the feed tube 7, is 'connected into the motor crank case by means of a tubular nipple 14. This connection int-o the crank case is approximately on a level with the free end of the feed tube 7, which is also the point of the low, or safe level of lubricant in the crankcase. The crank case, of some motors, has a pet cock, as 15 at the point of high level. The level of the lubricant in the crank case should range between these designated points of low, and high level.

The bottom of the chamber 13 also has a drain cock as 16.

There is a. disc-like valve 17 which works between the guides 6 and is adapted to open and close the outlet port. 5. A link 18 is pivoted, at its lower end, to this valve, and at its upper end to a disc-like inlet valve or sealing member 19 which works between the guides 20, depending from the upper end of the tank 1. The inlet valve 19has a central socket 21 into which the lower end of the rod 22 is fitted, and secured by the fl (l CAD cross pin 23. A filler plug 9A is adapted to he screwed over the upper end ot the rod and when sorevved heine, fits closely Within the inlet opening` Q5 in the 'top or" the tanl l and holds the inlet valve 19 seated closely against the top oi said tank. les shown the rod 22 has a loose connection with the pin so as to give the valve 1Q freedom to seat againstthe tank top ivith uniform pressure all the Way around.

lhen the plug,r 2l is serenf'ei'l heine the inlet control valve 19 and the outlet control valve 17 will he lifted for closing the oil inletand opening oil outlet, and when said plug is removed, for iilling` purposes the valves l? and 19 will drop, the i'oriner closinga to prevent the out "flow oit oil. n'lile the tank is being filled, and the latter opening; to perniit the filling ot the tank.

The upper face ol the valve has a1 annular `groove 2G therein which is l with oil during. the filling;` procesa When said valve 19 closed tl ped loetvveen said valve and the opposing; part of the top oi the tank l, `thus providing 4aneilective seal and rendering the joint airtight.

The link 1S is of suoli length that valves 1T and 19 niust open and close alternately.

In operation the oil Will he retained in the tank l While the inner end ol the nipple ll; and the lower end of fthe tnhe T are suhnierged. lllhen the level ot the oil in the crank oase falls loiv enough to uncover submerged ends, the air vvill ine-.mediatei;T enter through the feed tube T to relieve VAdie vaciuun in the tank l which will permit the feeding oi? the lubricant Trein the tank l into the crank oase. lllhen sniiicient nhricant .enters 'the crank case to raise the lubricant level therein above the inner end of the nipple M the air will he cnt .ofiQ and the Vfeed of lubricant will he temporarily stopped.

Part of the entering air will pass up through the transparent gauge ltuhe S in the .torni of huhhles and thns visibly indicate that the luhrieator is properi)T working.

The lubricator herein descrilied Vlepecially designed ttor use on internal conihnstion motors utilizing the splasl1""s};stein of lubrication and in which the reserve supply of oil is carried in the crank ease of .the inotor, wherein a constant .level oi" oil is to be maintained; and in which the circulation of the lubiicant isunaidedbvv the Alise oi a pump; and While .l have sho-Wn onlyv one forni of the device it is to `he und that various ineehanieal inoditieet' or adaptations nay 'he niade without departing; from the principle oit vthe inventi-fn embodied in the appended clain'is.
